See more Theorem: The theorem states that “the tangent to the circle at any point is the perpendicular to the radiusof the circle that passes through the point of contact”. Here, O is the centre and OP⊥XY. Theorem Proof: … See more i) If the point is in an interior region of the circle, any line through that point will be a secant. So, no tangent can be drawn to a circle which passes through a point that lies inside it. ii) When a point of tangency lies on the circle, … See more The length of the tangent from the point (Say P) to the circle is defined as the segment of the tangent from the external point P to the point of tangency Iwith the circle. In this case, PI is the tangent length. See more
